Abstract :Poly insert ignore into journalissuearticles values(N-isopropylacrylamide); insert ignore into journalissuearticles values(NIPA);-Graphene oxide insert ignore into journalissuearticles values(GO); composites were polymerizated radically with various contents of GO solution. The gelation process was performed by Steady State Fluorescence Spectroscopy. The results of gelation were modelled by Percolation and Classical Model, respectively. Our results show that the critical exponent of gel fraction is agree with percolation model till 25 µl content of GO solution. On the other hand, the optical energy band gap of the NIPA-GO composite was decided by using UV spectroscopy from the absorbance measurement in the range of 200-800 nm. The effect of graphene oxide dopant on the gap has been examined for NIPA-GO composites. In conclusion, their gelation process and optical energy band gap behavior were investigated and correlated to the GO content in the composites.
